Yonik Seeley commented on LUCENE-4242:
--------------------------------------
This patch doesn't seem to make sense.
liveDocsRatio will be the same for every term - if you want to take into
account deleted docs, then just do it when you set maxTermDocFreq.
Also, this code comes from Solr, where maxTermDocFreq is set as a percentage of
maxDoc - so things are already scaled by the number of deleted docs.
I don't think there's anything to fix here.
> UnInverted cache uses term freq to filter out terms (but deleted docs are
> included in the freq count)

> TermEnum.docFreq() count is used to compute uninverted index
> (DocTermOrds.uninvert()). The code goes like:
> final int df = te.docFreq();
> if (df <= maxTermDocFreq) {
> So, if there are deleted documents in the index and maxTermDocFreq is
> low, then the term will be excluded (even if the freq of the livedocs
> is OK). Most likely, the cache will be incomplete.
